I striped a hex 10mm hex bolt holding the cilinder header on a 98 dodge caravan 3.0L V6 engine with a torx socket

What do I do to remove it?

 

Im not sure what you mean by stripped the hex bolt with a torx socket? Torx is a male tool, you would have been using a "female" socket? Do you mean a 12pt socket vs. 6pt socket?

Either way, I havent been doing this stuff long enough to have picked up any techniques, but I would square it off with a dremel and use an open ended wrench to loosen it.

If there is enough room around the bolt, you can clamp a pair of vise grip pliers to it and
try to wiggle it loose. If the head of the bolt is rounded off too much to clamp on a pair,
You can create a large bead of metal on top of the bolt head with an arc welder, and then
use the pliers on the bead to try to break the bolt loose.

 

go to sears and get a stripped bolt/nut remover set. It will be the best 30 dollars you'll ever spend
